Heil Quaker ICP 1084734 Limit Switch
The Heil Quaker ICP 1084734 Limit Switch is a critical OEM safety component engineered for furnace repair and temperature regulation in ICP family equipment, including Tempstar, Arcoaire, and Comfortmaker units. This high-limit safety control features a 160-30 temperature rating, meaning it is calibrated to open the electrical circuit at a 160°F cut-out point to prevent heat exchanger damage and close at a 130°F cut-in point. As a genuine ICP replacement part, it ensures precise HVAC system diagnostics and reliable blower fan cycling, protecting the system from restricted airflow conditions often caused by clogged filters or failing blower motors. For technicians performing emergency heating repair, this SPST disc-type switch provides the exact thermal response curve required to maintain factory safety standards. Integrating This 1084734 limit switch into your service routine ensures compatibility across various air handler and furnace models, including the AMFK series, without the risk of improper calibration associated with universal alternatives.
Key Benefits- OEM Calibration: Factory-set 160-30 specs (160°F Open / 130°F Close) provide accurate overheating protection.
- Wide Compatibility: Direct-fit for Heil, Quaker, Tempstar, Comfortmaker, and Snyder General heating and cooling services.
- System Protection: Critical for prevents heat exchanger stress and potential fire hazards during high-static or low-airflow events.
- Durable SPST Design: Specifically built for high-cycle industrial and residential HVAC air handlers.
How do I know if my 1084734 limit switch is bad?
Common indicators include the furnace blower running continuously, the burners failing to ignite, or the system short-cycling. A technician can verify the 160-30 limit switch status using a multimeter to check for continuity across the terminals during a call for heat.
What causes a furnace high limit switch to trip?
The most frequent cause is restricted airflow. This is usually due to a dirty HVAC filter, blocked return ducts, or a failing blower motor that cannot move enough air to keep the heat exchanger below the 160°F threshold.
Can I use a universal limit switch instead of an ICP 1084734?
While some universal switches exist, using the genuine OEM 1084734 is recommended to ensure the cut-out and cut-in temperatures match the original engineering specifications for your specific furnace model.
